hmmm...not really sure. I don't think that a lowering module could be the culprit at all...I mean, that module lowers it what? 2-3" max? Barely enough to throw off your alignment...plus that would stress the suspension and not the wheels if anything. Are they 3-piece wheels (lip, face, inner barrel) and they're sending you new barrels? Are they forged? Either way that's disheartening for such a high-dollar product....especially if they're admitting to you that they're cheaping out on materials.
I'm not sure you can source new inners...especially in a larger diameter like that. I'd phone up any of the companies I listed...all of theirs are all custom-built so they might be able to do it (for a price, of course). Personally I'd get rid of the offending set of wheels for whatever I could get them for and put some HRE 944R or 948R's on it. Warranty too, so if it ever bends you'll have nothing to worry about.
